One of the biggest problems I have had with the Xbox since the 360 is batteries. You're either buying batteries frequently to replace what you just drained, or you get rechargeable ones that will die out on you in less than a year from use if you're a frequent gamer. So you're left with rechargeable battery ...

“Normally, a battery is charged and discharged to specific voltage limits, which is controlled by an electronic management system in the battery pack,” K.M. Abraham, an expert in this subject and a professor at Northeastern University, explained to Consumer Reports regarding what's causing the batteries to ...

Energy storage (batteries and other ways of storing electricity, like pumped water, compressed air, or molten salt) has generally been hailed as a “green” technology, key to enabling more renewable energy and reducing greenhouse gas emissions. But energy storage has a dirty secret. The way it's typically ...

It looks like Tesla is becoming a supplier for Elon Musk's Boring Company as the automaker confirms that they have an agreement with the startup to supply “certain vehicle motor and battery pack components.” Home Solar Power. Tesla confirmed the news last night in a proxy statement to shareholders for ...

NDSU assistant professor of Engineering Dong Zao says, in our current world of technology, while there are safer batteries which are less likely to explode, lithium-ion batteries are one of the cheapest out there, and can be applied for mass production. In the past you may have heard of cellphones, hover ...

Burnell Brown can't seem to escape the hundreds of hollow auto batteries encased in his basement. Or outside, in his retaining walls. All along the lakeshore of his White Bear Lake property. He'd noticed them decades ago. Worked close to them. Never in his wildest nightmares did the 72-year-old retired ...

From cell phones and laptops to electric vehicles, lithium-ion batteries are the power source that fuels everyday life. But in recent years, they have also drawn attention for catching fire. In an effort to develop a safer battery, scientists report in the ACS journal Nano Letters that the addition of nanowires can ...

The publication surveys 10 areas where batteries are transforming the energy system, from reducing demand charges to replacing peaker plants. It also proposes 50 actions nongovernmental organizations (NGOs) can promote to accelerate rates of battery storage adoption, including investigating new ...

Plans for Energizer to buy the Rayovac battery division moved a step forward this week when the deadline passed for federal regulators to object based on antitrust issues. The Portage Rayovac plant, shown here, is expected to be part of the $2 billion transaction, which the companies think will close in the ...

The world's biggest-ever solar project — a $200 billion venture in Saudi Arabia — comes with a “batteries included” sticker that signals a major shift for the industry. SoftBank Group has partnered with the oil-rich Saudis to plan massive networks of photovoltaic panels across the sun-drenched desert ...

YOKOHAMA, Japan — Nissan Motor Co. is downplaying the potential of solid-state batteries, a hoped-for breakthrough technology in electric vehicles. A senior Nissan technology executive called solid-state batteries' level of development "practically a zero" and warned that they face many hurdles before ...

There was fire at Rumpke's recycling facility in St. Bernard Thursday and a small battery is to blame. This isn't the first, second or even third time Rumpke has had difficulties with batteries. In 2016 alone, Rumpke officials said local fire departments had responded to at least six fires at the facility in Saint ...

Dendrites—branching structures that look like tree limbs—are fun to draw and good on neurons, but they're generally best avoided in lithium-ion batteries. As ions are exchanged between the anode and cathode over several charge and discharge cycles, lithium electrodes will sometimes grow dendrites ...

While batteries have been improving in recent times, at their core today's batteries still operate on the same basic electrochemical principles developed in the 18th and 19th centuries. Some physicists are now wondering whether quantum phenomena may revolutionize conventional battery chemistry and ...

Also, think about this: Bloomberg New Energy Finance is reporting that electric vehicles will cost less than gasmobiles in a few years because the cost of lithium-ion batteries is dropping super fast, and if you can wirelessly charge-on-the-go you will need smaller and even cheaper batteries, so put wireless ...

At the same time, Congress is considering a proposal to remove or reduce tariffs on more than 1,600 items — everything from the aforementioned peppers and batteries to pimientos and nonskid rings for toilet brush caddies. V. Formusa Co., a 120-year-old Des Plaines-based Italian foods manufacturer and ...

Lithium-air batteries sound too good to be true—using the oxygen available in the air to produce electricity. Theoretically, they could become serious competitors to lithium-ion batteries; but so far, a commercial reality hasn't emerged. Now, a team of researchers from the University of Illinois and the Argonne ...

Previous studies have had some success combining one-dimensional fibers with flexible Zn-MnO2 batteries, but many of these lose charge capacity and are not rechargeable. So, Chunyi Zhi and colleagues wanted to develop a rechargeable yarn zinc-ion battery that would maintain its charge capacity, ...

Lithium-ion batteries have proven successful for consumer electronics, but electric vehicles, wind turbines or smart grids require batteries with far greater energy capacity. A leading contender is the lithium-metal battery, which differs from lithium ion technology in that it contains lithium metal electrodes.

A partnership between developer Bay State Wind and NEC Energy Solutions this month highlighted a growing push to pair energy storage with offshore wind. Bay State Wind said it will work with NEC Energy Solutions to add batteries to an 800-megawatt offshore wind farm planned for 15 miles off the ...

"Common lithium-ion batteries only have a certain capacity," said Dr. Kyeongjae "K.J." Cho, professor of materials science and engineering. "And most people want to use their phones for a longer time." Many smartphone users are familiar with the shelf life of lithium-ion batteries. Sometimes a charge can ...

A German firm is aiming to help homes obtain year-round self-produced renewable energy with a hybrid storage system combining batteries with hydrogen. Zeyad Abul-Ella, managing director and founder of Berlin-based Home Power Solutions (HPS), said his company's Picea all-in-one unit, which went ...

China is hoping to become the Detroit of the battery-powered electric-vehicle industry. Sales of EVs are expected to reach 1 million this year alone, and the government has big plans for expansion. But this welcome trend comes with a perplexing side effect: China is now using up more lithium-ion batteries ...

Electric companies don't intend to use utility-scale batteries as storage. They want them for something just as important: ancillary services. In other words, they want batteries to bridge the gap between the time a power plant suddenly and unexpectedly goes off-line (trips), and backup power from another ...

Not so with button batteries. If one of these battery cells stops going and going—as the old Energizer tagline goes—and gets stuck in the food pipe, it will begin to conduct an electrical current, which raises the pH of the surrounding tissue. Within a few hours, if not removed, it can burn a hole through the ...

The method also works on lithium cobalt oxide, which is widely used in electronic devices such as smartphones and laptops. “In my house I have about six cellphones,” Chen said. “I have probably about five laptops. They all have lithium batteries. I thought, there is no clear system to recycle and retrieve ...

Cobalt is a fundamental cathode component in lithium-ion batteries (LIBs), determining the high energy and power density as well as the long lifetime. However, as outlined in the article by Dr. Christoph Vaalma et al., cobalt is toxic and scarce. "In general, the rapidly growing market penetration of LIBs for ...

The leader of the team that developed the battery, Professor John Andrews, says that with the improvements made possible by graphene, the proton battery could become a real challenger for lithium-ion batteries and advance efforts for energy storage solutions that pave the way for a renewable energy ...

Apple stresses that only a “limited number” of MacBook Pro batteries are involved. If your serial number does pop up, the site will advise you to bring the laptop to an Apple store or Apple Authorized Service Provider. According to the company, you can also mail your device to Apple. But it's not clear ...
